RESUMO

BACKGROUND: The study aimed to evaluate how maternal pre-pregnant body mass index (BMI) impacts participant recruitment and retention. METHODS: Participants were enrolled in a longitudinal study between 30 and 36 weeks of pregnancy as having normal weight (pre-pregnant BMI ≥ 18.5 and <25 kg/m2) or obesity (pre-pregnant BMI ≥ 30.0 kg/m2). Recruitment channels included Facebook, email, newspaper, phone calls, radio advertisements, flyers, and word-of-mouth. The stages of recruitment included eligibility, consent, and completion. Pearson's chi-square tests were used to evaluate the relationship between BMI and enrollment outcomes. RESULTS: Recruitment yielded 2770 total prospective participants. After screening, 141 individuals were eligible, 83 consented, and 60 completed the study. Facebook was the most successful method for identifying eligible pregnant patients with obesity, while a higher percentage of participants recruited through word-of-mouth and flyers consented to the study. Pre-pregnant BMI was significantly associated with the stage of recruitment completed by the participant (p = 0.04), whereby individuals eligible for the study with obesity were less likely to consent and complete study visits. CONCLUSION: We demonstrated that maternal obesity was significantly associated with enrollment outcomes in a longitudinal birth cohort study. This study showed that pre-pregnancy BMI influenced study participation. Therefore, tailored recruitment strategies to enhance the recruitment and enrollment of individuals with obesity in maternal-infant health research may be necessary.

RESUMO

Donor human milk (DHM) from a milk bank is the recommended feeding method for preterm infants when the mother's own milk (MOM) is not available. Despite this recommendation, information on the possible contamination of donor human milk and its impact on infant health outcomes is poorly characterised. The aim of this systematic review is to assess contaminants present in DHM samples that preterm and critically ill infants consume. The data sources used include PubMed, EMBASE, CINAHL and Web of Science. A search of the data sources targeting DHM and its potential contaminants yielded 426 publications. Two reviewers (S. T. and D. L.) conducted title/abstract screening through Covidence software, and predetermined inclusion/exclusion criteria yielded 26 manuscripts. Contaminant types (bacterial, chemical, fungal, viral) and study details (e.g., type of bacteria identified, study setting) were extracted from each included study during full-text review. Primary contaminants in donor human milk included bacterial species and environmental pollutants. We found that bacterial contaminants were identified in 100% of the papers in which bacterial contamination was sought (16 papers) and 61.5% of the full data set (26 papers), with the most frequently identified genera being Staphylococcus (e.g., Staphylococcus aureus and coagulase-negative Staphylococcus) and Bacillus (e.g., Bacillus cereus). Chemical pollutants were discovered in 100% of the papers in which chemical contamination was sought (eight papers) and 30.8% of the full data set (26 papers). The most frequently identified chemical pollutants included perfluoroalkyl substances (six papers), toxic metal (one paper) and caffeine (one paper). Viral and fungal contamination were identified in one paper each. Our results highlight the importance of establishing standardisation in assessing DHM contamination and future studies are needed to clarify the impact of DHM contaminants on health outcomes.

RESUMO

AIMS: Chronic Toxoplasma gondii infection is not thought to affect pregnancy or birth outcomes, but there are few prospective studies. The study aims were T. gondii immunoglobulin G measurement and relationship of chronic T. gondii infection with gestational age at birth and adverse pregnancy outcomes in 690 Hispanic women in Tampa, Florida. METHODS: Hispanic women, born either in the United States or in Latin America or the Caribbean had a venous blood sample drawn to measure T. gondii IgG and T. gondii serotype at the first prenatal visit, along with collection of demographic and health-related measures. Seropositive and seronegative women were followed throughout their pregnancy. Gestational age, infant weights, and adverse pregnancy outcomes (miscarriages, preterm births) were compared in the two groups. RESULTS: There were 740 women of self-reported Hispanic ethnicity screened and enrolled in Tampa, Florida, with 690 having birth data extracted from the electronic health record (538 T. gondii negative and 152 T. gondii seropositive). T. gondii seropositivity was 22.4% and the majority (83%) had high avidity titers, indicating chronic infection. Compared to T. gondii seronegative Hispanic women, seroseropositive women had more smaller for gestational age infants and higher prevalences of miscarriages and preterm birth. CONCLUSION: This is one of the largest longitudinal cohort studies of women with chronic T. gondii infection followed through pregnancy. There was a higher percentages of adverse pregnancy outcomes in this group compared to T. gondii seronegative controls. The mechanism for this is unknown and warrants reexamination of the dogma that chronic T. gondii infection in pregnant women has no significant clinical consequences.

RESUMO

Despite the numerous benefits that breastfeeding confers to those who breastfeed and their infants, the United States' exclusive breastfeeding rates and any breastfeeding rates at 12 months remain low and inequitable. This public health crisis has been prioritized in the US Healthy People 2030 goals. Current evidence-based practices to support lactation have afforded limited progress, thus, achieving national breastfeeding goals requires innovative ideas in thinking, technology, and care. This article highlights potential innovative strategies in the field of lactation to improve outcomes and work toward achieving health equity, while underscoring the critical role that perinatal caregivers play in lactation support.

RESUMO

Although sexual and reproductive health inequities acutely and disproportionately affect Black women in the USA, there are few studies that consider the sociocultural context in which Black women transition to adulthood and develop their sexuality. The objective of this study was to describe the lived realities of young Black women to elucidate how the sociocultural context informs their current perceptions of sexual and reproductive health. We conducted phenomenological interviews with 22 Black women aged 18-29 years to elicit their life stories. The main categories identified in the findings include how the sociocultural environment informs the self-concept; how the sociocultural environment informs early learning about sexual health; and how together these experiences inform women's development of a sexual self-concept. Three main groupings of experiences were identified relative to women's sexual self-concept: fear-based disease and pregnancy prevention; a deeper understanding of bodies and sexuality beyond disease and pregnancy prevention; and sexual pleasure and fulfilment as a priority. To address ongoing sexual and reproductive health inequities that particularly disadvantage young Black women, health systems and interventions should address the sociocultural contexts in which young Black women develop and manage their sexual health.

RESUMO

Women living below the federal poverty level have low breastfeeding rates and historically have lacked access to doula care. This disparity is particularly evident among African American women. The objective of this pilot study was to assess doulas' experiences delivering lactation education to racially/ethnically diverse, primarily Medicaid-eligible pregnant women and describe doulas' perceptions of client barriers to breastfeeding. We also wanted to understand doulas' views of infant feeding and lactation education during their participation in a quality improvement intervention that trained doulas to provide lactation education and breastfeeding support at 4 clinics serving low-income clients. Two focus groups were conducted with 7 doulas. Focus group data were transcribed, coded, and analyzed using qualitative thematic analysis. Doulas reported close relationships with their clients and provided consistent breastfeeding support and education to women in prenatal, birth, and postpartum phases of care. Doulas emphasized the need for more lactation education, especially to overcome clients' perceived milk insufficiency and early termination due to breastfeeding barriers. Doula-led breastfeeding education and support may improve breastfeeding outcomes for diverse women from underserved areas.

RESUMO

While family planning care (FPC) visits may serve as opportunities to address gaps in knowledge and access to limited resources, young Black women may also face structural barriers (i.e., racism, discrimination, bias) to engaging in care due to the intersections of racial identity, age, and socioeconomic status. Findings from interviews with 22 Black women, ages 18 to 29 years, about the lived experience of FPC highlighted dynamic patient-provider encounters. Women's narratives uncovered the following essences: silence around sex impedes engagement in care, patient-provider racial concordance as protection from harm, providers as a source of discouragement and misinformation, frustration as a normative experience, decision making excludes discussion and deliberation, medical mistrust is pervasive and a part of Black consciousness, and meaningful and empathic patient-provider encounters are elusive. Health systems should prioritize developing and enhancing young Black women's relationship with FPC providers to help mitigate persistent inequities that perpetuate disadvantage among this population.

RESUMO

OBJECTIVES: We sought to investigate the feasibility of a behavioral sleep intervention for insomnia, delivered through group prenatal care and the relationship of this intervention to improvements in insomnia symptoms and sleep quality. PARTICIPANTS: Women receiving prenatal care and reporting a pre-pregnancy BMI of ≥25 kg/m2 and sleep duration of <6.5 h per night. METHODS: Participants were randomized to group prenatal care or group prenatal care with a behavioral sleep intervention, adapted from cognitive behavioral therapy for insomnia (CBT-I) online program Go! to Sleep®. In the second trimester (T1), late third trimester (T2) and 6-8 weeks postpartum (T3) study assessments were completed including the Insomnia Severity Index, Pittsburgh Sleep Quality Index, fasting glucose and insulin and weight and height. Data were analyzed using independent samples t-tests, chi-square tests, correlations, and two-way repeated measures ANOVA where appropriate. P < .05 was set as the level of significance. RESULTS: From May 2014 to April 2015, 311 women were evaluated for inclusion and 53 women were randomized to participate (27 intervention; 26 control), 15% were lost to follow up. The intervention group had lower third trimester and postpartum levels of moderate to severe insomnia (T2 50.0% vs 85.0% (p = .018) and T3 13.6% vs 52.4% (p-.008)) and mean insomnia severity scores (T2 (14.7 (±6.6) vs 19.3 (± 6.0) p = .02) and T3 (9.7 (±5.4) vs 15.1(±7.2) p = .01)) when compared to the control group. CONCLUSION: A randomized controlled trial of a behavioral sleep intervention for insomnia delivered through group prenatal care led to improvements in insomnia symptoms.

RESUMO

OBJECTIVE: The objective of this study is to examine risk factors for neonatal abstinence syndrome (NAS) among infants born to mothers with sickle cell hemoglobinopathies (SCH). STUDY DESIGN: Retrospective cohort study of nonanomalous, singleton infants born to mothers with laboratory confirmed SCH. Infants were included if they were diagnosed with NAS prior to hospital discharge. The outcome of interest was the association of maternal variables with NAS. RESULTS: Of 131 infants born to mothers with SCH, 4% (n = 5) were diagnosed with NAS. Mothers of infants with NAS were more likely to have SC disease (80%) compared with other SCH (20%), p = 0.001. Fifteen women had antepartum (AP) admissions for pain and/or sickle crisis. Of these patients, four infants (29%) were diagnosed with NAS. The median (5th and 95th percentile) maternal AP length of stay for women with infants diagnosed with NAS to mothers with sickle cell disease was 132 (5, 180) days (p = 0.02). CONCLUSION: Incidence of NAS among mothers with SCH is low; severe disease characterized by AP sickle cell crisis requiring prolonged AP admission for pain control significantly increases the risk of NAS. Further studies are needed to investigate the association of maternal opioid dose and NAS.

RESUMO

OBJECTIVE: Mothers' return to work and childcare providers' support for feeding expressed human milk are associated with breast-feeding duration rates in the USA, where most infants are regularly under non-parental care. The objective of the present study was to explore Florida-based childcare centre administrators' awareness and perceptions of the Florida Breastfeeding Friendly Childcare Initiative. DESIGN: Semi-structured interviews were based on the Consolidated Framework for Implementation Research and analysed using applied thematic analysis. SETTING: Childcare centre administrators in Tampa Bay, FL, USA, interviewed in 2015.ParticipantsTwenty-eight childcare centre administrators: female (100 %) and Non-Hispanic White (61 %) with mean age of 50 years and 13 years of experience. RESULTS: Most administrators perceived potential implementation of the Florida Breastfeeding Friendly Childcare Initiative as simple and beneficial. Tension for change and a related construct (perceived consumer need for the initiative) were low, seemingly due to formula-feeding being normative. Perceived financial costs and relative priority varied. Some centres had facilitating structural characteristics, but none had formal breast-feeding policies. CONCLUSIONS: A cultural shift, facilitated by state and national breast-feeding-friendly childcare policies and regulations, may be important for increasing tension for change and thereby increasing access to breast-feeding-friendly childcare. Similar to efforts surrounding the rapid growth of the Baby Friendly Hospital Initiative, national comprehensive evidence-based policies, regulations, metrics and technical assistance are needed to strengthen state-level breast-feeding-friendly childcare initiatives.

RESUMO

A large urban hospital in Florida implemented changes to achieve the Baby-Friendly Hospital Initiative (BFHI) designation in 2015 resulting in an increase of exclusive breastfeeding rates at hospital discharge; however, African American women continue to have the lowest rates overall. Qualitative interviews were conducted with 20 African American women who received prenatal care at a low-income women's clinic and gave birth at an affiliated BFHI hospital. Using a medical anthropology analytical framework to examine predisposing, enabling, and service-related factors that affect breastfeeding, this study investigated interpersonal, sociocultural, and institutional barriers to breastfeeding. Common challenges experienced by participants included lack of maternity leave from work, lack of access to electric pumps, social pressures to initiate formula supplementation, fears that breastfeeding renders infants overly dependent on their mother's care, and a lack of breastfeeding role models and/or support networks to normalize longer-term breastfeeding. We conclude that efforts to increase breastfeeding rates for African American women and promote culturally sensitive interventions must address underlying socioeconomic and structural barriers, women's perceptions of breastfeeding benefits and difficulties, and the need for improvements in postnatal lactation and doula support to foster a more inclusive culture of breastfeeding.

RESUMO

Aortopulmonary window is a rare cardiac developmental anomaly characterised by a communication between the ascending aorta and the pulmonary artery. Aortopulmonary window may be isolated or associated with cardiac defects such as ventricular septal defect, atrial septal defect, interrupted aortic arch, and tetralogy of Fallot. We report a case of aortopulmonary window associated with aberrant subclavian artery based on fetal two-dimensional echocardiogram. The mother was referred for fetal echocardiography because of multiple fetal anomalies. Prenatal echocardiography at 30 weeks of gestation revealed a defect between the main and right pulmonary arteries and the ascending aorta (type III). The patient was born at 38 weeks of gestation via caesarean delivery, and was admitted to the neonatal intensive care unit because of respiratory failure and multiple congenital anomalies. Postnatal echocardiogram and cardiac MRI confirmed the prenatal findings. In addition, this patient had severe Dandy-Walker malformation and renal anomalies with poor prognosis. The family decided to withdraw respiratory care support on day of life 4, and the neonate passed away shortly after.

RESUMO

Objective Elevated homocysteine (HC) levels and/or shortened telomere length (TL) are associated with adverse medical conditions. Our objective is to investigate the relationship between HC and TL in cord blood leukocytes of newborns. Study Design This is a nested study from a prospective cohort from 2011 to 2012 in pregnant women admitted for delivery at a university-affiliated hospital. Cord blood was collected at delivery and genomic DNA was analyzed using quantitative PCR. The telomere-to-single copy gene ratio method was employed to quantify TL. Newborn HC levels were measured. generalized linear regression modeling (GLM) and bootstrap statistical analyses were performed. Results Seventy-seven maternal-fetal dyads with a mean gestational age of 39 weeks were included. The distribution of the coefficient of homocysteine showed most values greater than zero demonstrating that homocysteine had a positive relationship with TL. In 915 of 10,000 (9.15%) iterations, the p-value was < 0.05 demonstrating a positive effect. Conclusion Increasing newborn concentrations of HC are not associated with decreasing TL. Larger, prospective studies are needed to confirm these findings and long-term implications.

RESUMO

This review describes current understandings about the nature of the very low birth weight infant (VLBW) gut microbiome. VLBW infants often experience disruptive pregnancies and births, and prenatal factors can influence the maturity of the gut and immune system, and disturb microbial balance and succession. Many VLBWs experience rapid vaginal or Caesarean births. After birth these infants often have delays in enteral feeding, and many receive little or no mother's own milk. Furthermore the stressors of neonatal life in the hospital environment, common use of antibiotics, invasive procedures and maternal separation can contribute to dysbiosis. These infants experience gastrointestinal dysfunction, sepsis, transfusions, necrotizing enterocolitis, oxygen toxicity, and other pathophysiological conditions that affect the normal microbiota. The skin is susceptible to dysbiosis, due to its fragility and contact with NICU organisms. Dysbiosis in early life may resolve but little is known about the timing of the development of the signature gut microbiome in VLBWs. Dysbiosis has been associated with a number of physical and behavioral problems, including autism spectrum disorders, allergy and asthma, gastrointestinal disease, obesity, depression, and anxiety. Dysbiosis may be prevented or ameliorated in part by prenatal care, breast milk feeding, skin to skin contact, use of antibiotics only when necessary, and vigilance during infancy and early childhood.

RESUMO

BACKGROUND: Retinal photography was performed in pregnancy and postpartum in pregnant Hispanic women with latent Toxoplasma gondii (TG) infection in order to screen for characteristic retinal lesions or the particular scars found in people with active T. gondii infection. A comparison group of TG negative women was included in the study but they did not have retinal photography. OBJECTIVE: The goal of the parent study was to assess for adverse pregnancy events and evidence for parasite reactivation in TG positive (TG + ) women, through examination of the eyes for characteristic lesions. Retinal photography, usually at prenatal visits 2 (17 +/- 3.35 weeks) and 3 (26.3+/-1.75) weeks, was done on TG + women. Fifty-six of these women also (43 %) had retinal photography at the postpartum visit. Health and demographic data were obtained at the first prenatal visit for all women. STUDY DESIGN: From the 690 recruited at the first prenatal visit, 128 TG- women and 158 TG + women were enrolled in a prospective study through pregnancy and the postpartum. All TG- women (n = 532) provided data at the first prenatal visit and throughout their pregnancy and birth through the EHR. This allowed comparison of health and outcome data for the TG + compared to a larger number of TG- Hispanic pregnant women. RESULTS: While there was no evidence of ocular toxoplasmosis during pregnancy, there was a surprisingly large number (42 %) of TG + women with diabetic retinopathy (DR). We also observed that TG + women had a 20 % incidence of gestational diabetes mellitus (GDM) compared to 11.3 % in the TG- women (p = 0.01). At postpartum (mean 5.6 weeks), 23 of 30 women with pregnancy DR showed no DR in the postpartum. CONCLUSIONS: No characteristic T. gondii lesions were discovered. Retinal photography serendipitously revealed DR in these T. gondii positive women. It was also found that latent TG infection was associated with increased incidence of GDM. Hispanic pregnant women's increased risk for latent TG infection, GDM and DR are underappreciated. Retinal photography may need to be considered an innovative approach to screening.

RESUMO

Microbiome research has made significant gains with the evolution of sequencing technologies. Ensuring comparability between studies and enhancing the findability, accessibility, interoperability and reproducibility of microbiome data are crucial for maximizing the value of this growing body of research. Addressing the challenges of standardized metadata reporting, collection and curation, the Microbiome Working Group of the Human Hereditary and Health in Africa (H3Africa) consortium aimed to develop a comprehensive solution. In this paper, we present the Microbiome Research Data Toolkit, a versatile tool designed to standardize microbiome research metadata, facilitate MIxS-MIMS and PhenX reporting, standardize prospective collection of participant biological and lifestyle data, and retrospectively harmonize such data. This toolkit enables past, present and future microbiome research endeavors to collaborate effectively, fostering novel collaborations and accelerating knowledge discovery in the field.

RESUMO

INTRODUCTION: Bedsharing is common but advised against by the American Academy of Pediatrics. It is unknown if breastfeeding physicians bedshare more or less than the general population. OBJECTIVES: To determine the prevalence of bedsharing among physicians, their reasons for bedsharing or not, and whether bedsharing was associated with a longer duration of breastfeeding. METHODS: An online survey was adapted from surveys administered by the Centers for Disease Control and Prevention. The survey was administered to physicians and medical students who birthed children from October 2020 through August 2021. Respondents were asked to report on a singleton birth, and questions centered around sleep practices and breastfeeding. Survival analysis was used to examine the association between bedsharing and breastfeeding duration. RESULTS: Of 546 respondents with bedsharing data, 68% reported some history of bedsharing, and 77% were in specialties that involved caring for pregnant people and/or infants. Those who bedshared breastfed an average of four months longer than those who never bedshared (18.08 versus 14.08 months p<0.001). The adjusted risk of breastfeeding cessation was markedly lower for those who bedshared compared to those who did not (Hazard Ratio 0.57, 95% Confidence Interval 0.45, 0.71). The primary reason for bedsharing was to breastfeed (73%); the primary reason for not bedsharing was safety concerns (92%). Among those who bedshared (n = 373), 52% did not inform their child's healthcare provider. CONCLUSIONS: Bedsharing is common among our sample of mainly breastfeeding physicians, including those who care for pregnant people and/or infants. It is also associated with a longer duration of breastfeeding, which has implications for population health. Practicing bedsharing implies cognitive dissidence and may affect how physicians counsel about bedsharing. Additionally, lack of disclosure of bedsharing practices has implications for practical guidance about having open non-judgmental conversations and may be a missed opportunity to counsel on bedsharing safety.

RESUMO

INTRODUCTION: Cortisol is a biological marker of stress, and its levels reflect the hypothalamic-pituitary-adrenal (HPA) axis response to stress over time. Saliva, blood, and urine cortisol reflect acute stress, whereas assessment of hair cortisol is a better reflection of chronic stress. There is limited information on hair cortisol concentration (HCC) in the perinatal period, particularly, in the preconception and postpartum periods. In addition to being a biomarker for stress, high levels of cortisol are typically associated with poor psychosocial outcomes, and adverse pregnancy outcomes. The objectives of this study were: (1) to measure HCC from six months preconception to six months postpartum; (2) to examine the relationship between HCC and demographic characteristics, depressive symptoms, and perceived stress in the first six months postpartum period; (3) and to assess the associations between HCC and systemic inflammatory markers in the first six months postpartum. METHODS: The analysis included 96 women from a longitudinal study with up to 3 study visits in the first six months postpartum. Blood and hair samples were collected at 1-2 months (PP1), 3-4 months (PP2), and 5-6 months (PP3) postpartum. We obtained sociodemographic information, depressive symptoms, and perceived stress scores at PP1-PP3. To quantify cortisol levels over time, 8 segments were derived corresponding to 6 (PC1) and 3 (PC2) months preconception as well as for each trimester (T1-T3) and postpartum (PP1-PP3). Eight cytokines (Granulocyte-macrophage colony-stimulating factor (GM-CSF), Interferon- gamma [IFN- γ], Interleukin [IL]-10, IL-2, IL-4, IL-6, IL-8, and Tumor necrosis factor-alpha (TNF- α) were measured in plasma in the postpartum samples. Univariate, bivariate, correlations, and linear mixed modelling were performed using SAS 9.4. Multiple testing correction was conducted for correlations using false discovery rate and a Q value of <0.05 was deemed significant. RESULTS: Median HCC varied over time peaking in the third trimester and declining in the postpartum. Significant differences were noted in median cortisol levels by race with Black/African American postpartum women experiencing higher levels at all timepoints. Significantly, higher median cortisol levels were also observed at PP1 and PP2 for mothers who reported their relationship status as single. Ethnicity, education, median age, depressive symptoms, and perceived stress were not associated with median cortisol levels. Pro-inflammatory cytokines IFN- γ (q= 0.01; r=-0.50) and IL-8 (q= 0.00; r=-0.55) showed correlations with HCC at PP1. CONCLUSION: HCC increased during pregnancy, peaking at T3 and declining PP consistent with previous work. Black/African American women and single women have significantly higher median cortisol levels in the postpartum period. The marked increase of HCC in Black women may be an important factor in understanding maternal health racial inequities. Future studies should investigate how the relationships between HCC, sociodemographics, and systemic cytokines impact perinatal outcomes.

RESUMO

BACKGROUND: Maternal mortality rates continue to rise in the United States. Considerable racial disparities exist, as Black women face two to three times the risks of dying from pregnancy-related complications compared with white women. Doulas have been associated with improved maternal outcomes. This study aimed to 1) investigate Florida doulas' perspectives and influence on severe maternal morbidity/mortality and related inequities, as well as 2) identify opportunities for actionable change. The social ecological model, which acknowledges how individual, interpersonal, institutional, community, and public policy factors intersect, informed our analysis. METHODS: This qualitative study included seven online in-depth interviews and seven focus groups with doulas (N = 31) in Florida. Interview guides investigated how doulas perceive their role in the context of a) maternal morbidity and b) health disparities. RESULTS: Doulas associated maternal morbidity and health disparities with Black pregnant people, identifying racism as a major contributor. Doulas identified their role as one that most often intersects with the individual and interpersonal levels of the social ecological model. Doulas report providing positive social surveillance and emotional support, contributing education and resources, and championing for advocacy in health care settings. Actionable steps recommended by doulas to further mitigate health disparities include the integration of implicit bias training into doula certification programs, increasing public health funding to bolster a doula workforce that can serve racial and ethnic communities, establishing doula-hospital partnerships to improve relational communication, providing tailored resources for clients featuring representative messaging, and doulas' continued engagement in positive social surveillance of their clients. CONCLUSIONS: Doulas perceived their role as integral to mitigating maternal morbidity and health disparities, particularly in the context of supporting and advocating for birthing persons on all levels of the social ecological model. Equitable access to doulas for low-income and/or minoritized populations may be one key strategy to improve maternal health equity.
